What is semiconductor in simple words?
What is a semiconductor? Semiconductors. Semiconductors are materials that have a junction between conductors (usually metals) and non-conductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide.

The CPUs used in personal computers are also made of semiconductors. Many digital products in everyday life such as cell phones/telephones, digital cameras, televisions, washing machines, refrigerators and LED light bulbs also use semiconductors.
Why is it called a semiconductor?
The semiconductor is called a semiconductor because it is a type of material that has an electric current that is between the standard resistance of metals and the standard resistance of insulators, that is, or “semi” – it conducts electricity.

A widely known semiconductor is silicon. Electronic components that use semiconductors are called semiconductor devices, including an IC, which is an integrated network of transistors. Semiconductor devices embedded in many electronic devices are important electronic devices that support our daily life.
Why are semiconductors used instead of conductors?
In Conductors, there is total current flow (Zero resistance). Semiconductors, can act both as an insulator as well as a conductor based on electricity. Therefore, there is an opportunity to control the current flow in semiconductors.
What is semiconductor and example?

Who invented semiconductor?
History of Semiconductors In 1874, Karl Braun discovered and recorded the first use of the semiconductor diode. Braun observed that it flows freely in one direction at the interface between a metal and a galena crystal. In 1901, the first semiconductor device, called the "cat whiskers," was patented.
Which country invented a semiconductor? The history of the birth of semiconductors can be traced back to the invention of the rectifier (AC-DC converter) in 1874. Many years later, Bardeen and Brattain built it at Bell Laboratories in the US the point-contact transistor in 1947, and Shockley made the junction. transistor in 1948.

When was the first semiconductor used?
The first use of semiconductors in electronics was the development in 1904 of the cat’s-whisker detector, a semiconductor diode first used in the first radio. Developments in quantum physics led to the invention of the transistor in 1947, the integrated circuit in 1958.
What are the 3 properties of semiconductors?
4 Important Properties of Semiconductors
- Property 1: The resistivity of a semiconductor is less than that of an insulator but higher than that of a conductor.
- Property 2: Semiconductors exhibit a relatively poor temperature resistance. …
- Property 3: At zero kelvin, semiconductors behave like insulators.
What determines the property of a semiconductor? The properties of semiconductors are determined by the energy gap between valence and conduction.
What are three semiconductors?
The most commonly used semiconductor materials are silicon, germanium, and gallium arsenide. Of the three, germanium was one of the first semiconductor materials to be used. Germanium has four valence electrons, the electrons in the outermost shell of the atom.
What are the main semiconductors?
The elements include antimony, arsenic, boron, carbon, germanium, selenium, silicon, sulfur and tellurium. Silicon is the most popular of these, forming the basis of many ICs. Common semiconductor compounds include gallium arsenide, indium antimonide and the oxides of many metals.
What are the types of semiconductors?
Semiconductor is divided into two categories: Intrinsic Semiconductor. Extrinsic Semiconductor.
